HOOD AND IGNITION LOCK FOR .AUTOMOBILES.

Application filed May 13, 1924. Serial No. 713,049.

To all whom it may concern; venient means for lifting said body which Be it known that I, PETER O. PrNKER'roN, is here shown as hollow and enclosin the a citizen of the United States, residing at spring 17 surrounding an anchor bo t 18 Indianapolis, in the county of Marion and having a nut 19 at its upper end. A nut 20 v State of Indiana, have invented certain new has threaded engagement with the hollow 60 and useful Improvements. in Hood and body at its lower end, said nut having an Ignition Looks for Automobiles, of which opening loosely surrounding the anchor 18, the following is a specification. The nut 20 is held against rotation by one My said invention relates to a hood and or more pins 21 passing through the wall of ignition lock for automobiles and it is an body 16 into holes in the nut. '65 object of the same to provide a device of At its lower end the anchor has lateral this character which shall provide an efliprojections '22 resting in a downwardly cient lock for the hood as well asfor the opening slot of a block 23. This block is ignition and thus provide means for safesecured to the frame member 10 by means guarding automobiles from theft. of bolts 24 passing upward through holes in 70 Further objects are to provide a device the frame member and having threaded enwhich is-not likely to operate automatically gagement with holes in the block.

When it is desired to lock the hood and the ignition the key 35 is inserted in the plug and the bolt is turned into the full line position of Figure 3 which is the heavy line position of Figure 4, the arm 30 being somewhat beveled to force the standard 33 slightly back so that the arm can come into engagement with the screw 31 and the arm resting at its rear side against the hood. This grounds the circ'uit through the timer and at the same time brings the catch 30 into the dotted line position of Figure 5 where it presses firmly against the hood to prevent withdrawal of the latch from the hood and so prevent raising of the hood.

Various modifications of my device will beobvious to those skilled in the art and therefore Ldo not limit myself to what is shown in the drawings and described in thespecification, but only as indicated in the appended claims.

Having thus fully described my said invention, what. I claim as new and desire to secure by Letters Patent is:

l. A hood and ignition lock for automobiles comprising a latch for the hood, a bolt carried by the latch having an end projecting through an aperture in the hood, a laterally projecting arm on the bolt adapted in one position to prevent withdrawal of the latch, and a contact located underneath the hood in position to cooperate with said laterally projecting arm to ground the ignition circuit, substantially as set forth.

2. A hood and ignition lock for automobiles comprising a latch for the hood, a bolt carried by the latch having an end projecting through an aperture in the hood, a laterally projecting arm on the bolt ada ted in one position to prevent withdrawal of the latch, a resilient standard under the hood, and a contact on said standard adapted to cooperate with said lateral arm to ground the motor circuit, substantially as set forth.

3. A hood and ignition loclr for automobiles comprising a hollow body, a-lateral arm adapted to engage an aperture in the hood, a block on the frame of the machine, an anchor bolt pivotally connected to said block and projecting into the hollow body, a spring surrounding said anchor bolt, and means at the ends of the spring for confinuna ing itwithin the hollow body, said means being connected respectively to the body and the bolt, substantially as set forth.

4. A hood and ignition lock for automobiles comprising a block having a downwardly opening slot, bolts projecting upward through a part of the frame into threaded engagement with said block, an anchor bolt having laterally projecting arms in said slot and an upwardly projecting portion, a latchresiliently connected to said portion, and a bolt on said latch for locking the latch in engagement with the automobile hood, substantially as set forth.

5. In a hood and ignition lock for automobiles, a pivoted latch, a hook on the latch, resilient means for holding the hook in latching position relative to the hood, and a bolt on said latch adapted to have locking relation with the hood, substantially as set forth.

6. In a hood and ignition lock for automobiles, a pivoted latch, a catch on the latch, resilient means for holding the catch in latching position relative to the hood, and a bolt on said latch adapted to have locking relation with the hood said bolt also cooperating with a contact to ground the ignition circuit, substantially as set forth.

7 In an ignition lock for automobiles, a standard under the hood having an offset portion at its upper end, a fiber strip projecting upward from said ofi'set part, a contact on the fiber strip, and a rotary contact adapted to engage the first contact for grounding the circuit, said rotary contact normally projecting over the shoulder formed by the offset, substantially as set forth.

8. In an ignition lock for automobiles, a standard under the hood having an offset portion at its upper end, a fiber strip projecting upward from said offset part, a contact on the fiber strip, and a rotary contact adapted to engage the first contact for grounding the circuit, substantially as set forth.

In Witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana this 9th day of May, A. D. nineteen hundred and twenty-four.
